  This test checks that <code>:focus-visible</code> matches after a keyboard event,
  even if the event handler calls preventDefault() on the event.
  <ul id="instructions">
    <li>Click "Click here and press right arrow.".</li>
    <li>Press the right arrow key.</li>
    <li>If the element has a red background, then the test result is FAILURE.
        If it has a green outline, then the test result is SUCCESS.</li>
  </ul>
  <br />
  <div id="target" tabindex="0">Click here and press right arrow.</div>
